ELECTRlCALLY-GOVERN ED SWITCH.

N0- 4,?47: in Austria-Hungary February 12, 1892, No. 8,300; in England February 13, 1892, No. 2,849; in France February 18, 1892, No. 219,509; in Belgium February 18, 1892, No. 98,419, and in Italy March 5,1892,

To aZZ whom it may concern- Be it known that I, EMIL HUGO ERNST KLATTE, a subject of the Grand Duke of Baden, German Empire, residing at Freiburg, Baden, Germany, have invented certain new and useful Improvements in Electrically-Governed Switches, (for which I have obtained patents in the following countries, to wit: Germany, No. 65,039, dated February 7, 1892; Belgium, No. 98,419, dated February 18, 1892; France, No. 219,509, dated February 18, 1892; England, No. 2,849, dated February 13, 1892; Austria-Hungary, No. 8,300, dated February 12, 1892; Italy, No. 31,394, dated March 5, 1892, and Switzerland, No. 4,747, dated February 11, 1892,) of which the following is a specification.

This invention relates to an electric device for operating rail road switches and which is especially adapted for switch towers or stations: and the invention consists in the combination with an electro motor, of switch tongues operated by the motor, accordingly as the armature of the motor is rotated in one direction or the other.

The invention also consists in the construction and combination of parts and details which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan-view of my improved electric switch operating-device, parts being omitted. Fig. 2 is a side-view of the electro motor. Fig. 3 is a detail-plan-view of the automatic circuit breaker. Fig. 4 is a plan-view of the pole changing device in three different positions,

and Figs. 5 and 6 are diagrammatical planviews of the electric conductors for operating the switches.

Similar letters of reference indicate corresponding parts.

Upon the shaft of the electro motor G, which may be of any approved construction, a worm F is formed, that engages a work-wheel E fixed on the screw spindle D that is suitably mounted in bearings adjacent to the switch tongues A A. A nut C is mounted to travel on the spindle D and is connected by the connecting rod B with one switch tongue, the two tongues being connected by the rod B.

When the motor is operated by admitting a current into the same, the screw spindle D is rotated in one direction or the other, and accordingly the nut C is moved in one direction or the other and the switch tongues moved likewise. When the switch tongues are thrown it is necessary that the current should be broken a short time before the switch tongues rest against the corresponding rails, so that the inertia of the machine is just suificient to press the tongues firmly against the rails. For the purpose of accomplishing this, the automatic circuit breaker shown in Fig. 3 is provided. The arm H is so pivoted that it can rest upon either one of the two contact pieces J and K. Upon the upper rounded end of the arm H a spring W bears, which has a tendency to swing the 0pposite end of the lever outward or against the stop pins 0, which stop pins a hold the end of the lever H on the ends of the contact pieces J and K. A reciprocating rod L is arranged under the lever H and is provided with two projections M N, which can act upon the lever H, which rod L is connected in any suitable manner with the nut C, so as to participate in the movements of the same.

When the parts are in the position shown in Fig. 3 and the rod L is moved to the right,

the projection N acting against the lever H swings the same from the position shown in full lines in the direction toward the position shown in dotted lines. When the lever H has arrived slightly past the median line, the spring W, which is in tension, throws the same forcibly into the position shown in dotted lines, whereby the current is broken and shut 0E from the motor, the inertia of the motor being sufficiently great to move the screw spindle to such an extent that the switch tongues are pressed firmly against the rails. For the purpose of moving the switch tongues from one position to the other, it is necessary to conduct the current into the motor in the reverse direction. This is accomplished by means of a pole changer O,

which is shown in difierent positions in Fig; 4. This pole changer is constructed with two opposite insulated contact pieces P Q, of which P is connected with the positive conductor to the source of electricity and q with the negative conductor. By giving said current changer a quarter turn the current is interrupted completely, as shown in the center of Fig. 4, and by giving a further quarter turn in the same direction the current is reversed.

At the central station a pole changer O and the electric switch V are provided for each pair of switch tongues.

From the pole changeraconductor R passes to the motor G, and from the two conductors of the electric switch V two conductors S T extend to the contacts J K previously described. When the parts are in the position shown in Fig. 5, the current passes from the positive contact piece P through the conductor R to the electro motor G, and from the latter through the switch H, conductor S, and switch V back to the negative contact piece Q of the pole changer O. The screw spindle D is-now rotated and moves the switch.

tOngueS.

When the tongues are quite close to the rails the lever His thrown in the manner described and the current broken. If now the switch tongues are to be moved back into the original position, the official at the central station reverses the pole changer O and adjusts the switch V in such a manner as to make connection with the conductor T. The current now passes from the positive contact piece P of the pole-changer through the switch V, conductor T and the lever H to the electro motor G, and from the same through the conductor R back to the pole changer. The electro motor is now operated in the reverse direction and the switch tongues are also moved in the opposite direction. The pin M now pushes the lever H from the position shown in dotted lines in Fig. 3 toward the position shown in full lines.

By means of the above described device, any number of switches can easily be manipulatedfrom a central station, and said switches can be located any desired distance from said central station and do not require the expensive, cumbersome and unreliable rods or wires or pulleys used heretofore.

I-laving thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. The combination of a railway track, a railway switch tongue, an electric motor connected with the switch tongue for operating it, a circuit breaker connected with the switch mechanism, and a pole changer connected with said motor and circuit breaker and adapted to reverse the motion of the electric motor for shifting the switch tongue.
